Yes I have a scrubber, it's been working very well and going crazy with all the die off. I also have a skimmer built into the sump which I've only used to remove the ich med. everything I read online about pathogens leads me to believe they're species specific. If it weren't for trying to play coral medic I would believe it to be overkill on lights or a tank cycle, as I did remove all my fish. Could this be so simple as a tank re cycling?
Thanks.
